Timztoy is right...didn't realize 81 was the cutoff.
1984 to 1982 dyne test - 1981 & older tail-pipe test - 1975 & older no test
All dyne tests require 33s or smaller because their equipment can't handle larger tires. Keep in mind the dyne tests were created to test your vehicle under real world conditions so changing to a smaller tire kind of defeats their logic.

Call the Toyota document folks and request the emissions manual for your year. The book covers both Federal and California emissions. Lots of diagrams and pictures.
